On my new 38GL950G-B my refresh rate randomly drops. I've seen it drop from 144Hz to 85hz after playing a game. I've woken it up from deep sleep and it went from 175Hz to 60hz. When going back into the Nvidia Control Panel I have not seen anything above 85Hz available. I have to shut the monitor down before all other choices show back up It is connected via a display port 1.4 cable. It has not changed while playing a game I wish I could provide more information but the issue seems very random. Any information would be appreciated.
